- Approximate ln 2 using the 3'rd degree Taylor Polynomial. Find the error term.
- Find the 4th degree Taylor Polynomial centred around $a=0$ of $f(x)=e^x$. Then approximate $e^2$.
- Find the 2nd degree Taylor Polynomial centred around $a=1$ of $f(x)=\sqrt{(x+1)}$ and the error term where $x \in [0,2]$.
- Show that $f(x)=e^x$ can be represented as a Taylor series at $a=0$.
- Show that $f(x)= \cos ?x$ can be represented as a Taylor series at $a=0$.
